DVB-T，DTMB简化的信道仿真程序。设置了三种保护间隔：循环前缀、零添加、伪随机添加。用于研究不同保护间隔下的SNR特性，附带一个不同保护间隔下的频谱显示，可看出三种保护间隔对OFDM频谱陡峭程度的影响。(DVB-T，DTMB channel simulation and spectrum display.)

有一个3阶对象，要求使用继电自整定方法对其实施自适应PID控制。 要求： 1、选择采样时间0.1s，把对象离散化。 2、加继电（开关）控制，测量对象的Tc,Kc。 3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。 4、实现闭环控制。 5、根据调节效果，修正PID参数。 (A 3-order object, requires the use of relay self-tuning PID control methods on the implementation of adaptive. Requirements: 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)
